To all whom it may concern Be it known that I, Fnarzn BISEK, a citizen of the United States, residing at Alenandria, in the county of Douglas, State of Minnesota, have invented certain new useful improvements in Ice-Cuttin Machines; and i do hereby declare the f0 lowing to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to motor operated ice cutting machines.

The principal object of the invention is to provioe an ice cutting machine of the character described in which there is provided a novel construction of tractor Wheel for the sonic.

Another object of the invention is to provide a machine of the character described in which there is provided separate means for elevating boththe tractor wheel and the saw.

Another object of the invention is to pro vide an ice cutting machine including a frame having transversely disposed runners attached thereto and means for raising and lowering said runners.

A further object of the invention is to provide an auxiliary saw for cutting a groove in the ice, in which one of the runners of the frame is adapted to ride, and

by means of which uniform strips of ice.

may be cut.

A further object of the invention is to provide a novel form of gearing for the tractor wheel whereby said Wheel may be rotated in either direction.

A still further object of the invention is to provide a machine of the character described, which is extremely simple in construction, is capable of being operated by one person, and is cheap to manufacture.

With these and other objects in View, the

invention consists in the construction and novel combination parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in. the claims hereto appended; it being understood that various chmlgc's in the form. proportion, size and minor de-ails of construction within the scope of the claims, may be resorted to withol'it cleparting'froin the spirit or sacrificing any of the advantages of the invention.

Like reference numerals designate correspending parts in all the figures of the drawings.

lefcrring to the drawings, the invention comprises a main frame which includes lower longitudinal sills 5 and 6 respectively, Whichare connected at their ends by lower end sills 7 and 8 respectively. Secured to the respective ends of the frame are front uprights 99 and rear uprights 1010. The upper ends of these uprights are con- A. cover is provided for the machine as clearly shown rcsting upon the sills 7 and 8 in Fig.6 of the drawings.

Secured to the lower ends of the uprights 10 are bearings l1-l1, which are transversely disposed in alinemcnt, and mounted in these hearings is a transverse shaft 12. One end of this shaft extends beyond the longitudinal sill 6 of the frame, and has attached thereon a sprocket Wheel 13. Connected to the bearings 11 and extending rearvmrdly therefrom are spaced. arms 1l-H which form part of a tractor Wheel frame. Thesearms are held against lateral movement by means of cross braces l5-15. Mounted upon the outer ends of the arms 14 are bearings l6-'1G,/--Wl1i ll1 are disposed in alinernent and in which is mounted a shaft 17. Rotatably mounted upon the shaft 17 is a plurality of spaced supporting elements 18 and to the rims thereof are connected a plurality of longi' tudinal bars 19, the elements and the bars constituting a rotating-- cylinder. Secured from is a plurality of pointed teeth 20 adapted to engage the ice to propel the mo.-

a guard frame,

chine, as will be hereinafter more fully errlained. In order to rotate the tractor wheel there 'is mounted upon the shaft 17 between the outer elements 18 and the adjacent bearing 16, sprocket wheels 21-21 which arerespectively connected by chains 2222 to gear Wheels 23-23 mounted upon the shaft 12. .A platform 2t is suitably connected to the main frame, and is disposed between the frame and the tractor wheel and above the supporting arms 14%. Secured to the outer end of each arm l-l is which includes a vertical arm 25 and an arcuate! arm 26. Connecting the arcuate arms 26 of the guard frame is a guard late 27, said guard plate being disposed in spaced relation to the teeth 20 of the tractor wheel. 5

A motor 28 of any suitable type is supported upon the main frame by means 0 braces 29, and this motor includes the usual driving shaft 30 and fly wheel 31. Also secured upon the driving shaft 30 is a pulley A. countershaft 33- is transversely supported in bearings 3%34, which are carried by the lower longitudinal sills 5 and 6 of the frame. This shaft is disposed slightly in advance of and below the driving shaft 30 of the motor. Secured upon this shaft. is a pulley 35 which is in alinement with the pulley 32, and is operatively connected therewith by means of a belt 36. Also secured upon the shaft 33 isa friction wheel 37, which is always in mesh with a friction idler 38, the latter being mounted upon a second countershaft 39, which is transversely disposed and supported by brackets 40-40 mounted upon the lower sills 5 and 6 of the frame. Secured upon lower longitudinal sill 5 of the main frame in rear of the idler 38 is an arcuate bracket 41, see Fig. 8 and radially and upwardly projecting from the central portion of the bracket are spaced blocks 42-42 which are each connected to the bracket by means of a bolt 43. Disposed upon the outer ends of the blocks is an arcuate bar 44: through which the bolts 43 pass, and is secured in place by means of nuts .5 engaged with the bolts 43.

lidably mounted between the bracket 4-1 and the bar 4-4- is a bearing block it), in

which is mounted one end of a third countershaft 47. This shaft extends across the frame and the other end of said shaft is journaled in a bearing 48 mounted upon a bracket 49, which is carried by the longitudinal sill 6 of the frame. Securedupon the shaft 47 is a friction gear 50, which is adapted to mesh with the idler 38. A fourth countershaft 51 is disposed in rear of and below the shaft 47, and has its ends journaled in suitable bearings formed in the tion gear 50 when the latter is which is fulcrumed to a bracket 54carried by the main frame and directly in advance of the platform 24:. T he lower end of the lever 53 is connected to one end of a rod 7 55, the other end of the rod being connectedto a block 56 mounted upon the shaft 47 and disposed between the bracket 41 and the bar 44.. it will thus be observed that upon forward movement of the lever 53 the friction gear 50 will be forced into engagement with the idler 52, and. upon rearward move ment of the lever 53, the gear 50 will be disengaged from the idler 52 and engaged with the idler 38. Mounted upon one end of the shaft 47 is a sprocket wheel 57 which is in alineme'nt with the sprocket Wheel 13,

and is connected therewith by means of chain 58. A plurality of different size to either of the idlers 38 v or 52, there is provided a hand lever '53,

sprocket gears 59 are mounted upon the shaft 51, and

versely arranged sprocket wheels 60, any pair of said gears 59 and 60 being adapted to be connected by means of a chain 61.

It will thus be observed that in driving the machine forward motion is transmitted from the engine shaft 30 to the shaft 33, thence through the gear wheel 60, chain 61 and gear 59 to the shaft 51. Thence, by means of 50, thence by means of the shaft 47 to the sprocket gear 57, and by means of the chain 58 to the shaft 12 and from said shaft to the tractor wheel. When it is desired to reverse the tractor wheel, the hand lever 53 is moved rearwardly to draw the friction gear 50 in engagement with the idler 38. As a result, the rotation of the tractor wheel will be reversed, by reason of the fact that the idler 38 is disposed directly between the friction gears 37 and 50.

The shaft 33 projects beyond the side sills 5 and 6 of'the' main frame, otally supported on said projecting ends are forwardly extending arms 6262 formframe, and secured upon the projecting end i of each arm is a bearing 63. Disposed within-these bearings is a saw arbor 6 which carries a circular saw 65, said saw being disposed at one side ofv the main frame and preferably on that side on which the operating lever 53 is disposed. The diameter of the saw 65 is of a size to project considerably below the frame when the arms 62 are in their normal or horizontal posi tions.

the idler 52 to the friction gear mounted upon the shaft 33 and in ahnement with said gears 59 are rewhen ii; is to oliifii ine ironic leierelly the trocior wheel and. the new will izn ezorily here "to he rail-ed and ordr to effect this operation, I have provided following mechanism: Mounted upon the rear uprights l0 and adjeceni; the upper ends lherecf are hearings o=3-86. Mounted "within the bearings 61' is o. ironcversc shaft said shaft projecting beyond the ends of the uprighce 1o. Mounted upon one oi the projcciing ends is a hood wheel 68, by

roe-one oi? which the shaft 6T can be rotated." Loosely mouneecl upon the shaft 6'? 1S ow loos 8% will he rolelzed to sleeve 69 to which is attached e. hand Wheel.

70, the latter being on the opposite side of the machine from the hand wheel 68 and being adopted i0 rotate the sleeve.- Finedly mounted upon the sleeve is o Windinydrum 71 to which is connected the ends oi cables 7272. Elecured to the upper end sill 8 and projecting rearwardly therefrom are spaced. breclreis "iii- 33, and journuled in said brackets is a shaft 7 upon which is loosely mounted or roller 75 over which the cables 72 pass, Also mounted upon the end eill 8 in advance of the roller 75 erespuced brackets 7\3-T6, in which is journaled 2 smaller roller 77 over which. ithe cables 72 are trained. The other ends of the cahlee 72 are fixedly connecied to clips 78 78 carried by the guard plate 27' of the tractor wheel. it will thus he observed that upon rotation in one direction of the hand. Wheel 70 ihe sleeve 69, and consequently the drum 71, will be rotated and the tractor wheel frame will he swung upwardly upon the shaft 12. Secured upon the sleeve 69 is o ratchet wheel 79, and pivotally secured upon the adjacent upright 10 is a dog 80 adapted for engagement with any of the ratchet teeth to hold the drum 'Zl against rotation, and thereby retain the tractor Wheel frame in its elevated position. Secured upon the upper ends of the uprights .9 are uliued bearings 8181 and journaled in said bearings is a shaft 82, upon which is secured a sprocket wheel 83 adapted to receive motion through means of a sprocket chain 84: which is trained over a sprocket Wheel 85 mounced upon the shaft 67. The

shaft projeccs beyond the uprights 5) of the frame, and mounted upon each projecting end of the shaft is a pinion 86. Guide plates 87 are each pivot-ally mounted upon the shaft 82 around a respective pinion 86. Slidably mounted within each of the guide plates 87 is a rack oar 88, the teeth 89 there of being engaged with the respective pinion 86. Carried by each of the guides 87 are rollers 87 which engage the longitudinal edge of the rack bar opposite the teeth 89 thereof, so as to permit said bar to easily slide within the clip. Secured to the foe Ward end of each arm 62 of the saw sup-' porting frame is an inverted ll-sl1aped clip v Mo's Law $30, the logo 91 iiecied to 5:, hole $25, i in e rsuiixziilc op A tum buckle F23 iizs code to the oi the clip will anus he observer izhoi; upon rol tion of ihe hand wheel. in one the cproclret wheel will rotoied, and as e reculi, motion will be imported through die chain 8 lo the for-Word shaft 82., l" through the ro'mliou of ii shah; iio p ,llSE: the rock hers @8 and consequently the sow frame. Mounted upon the forward ifihe lower longitudinal sills and 6 are brackets 94- 2% suppori/ed upon theoe bracketsure hearings 95-495 in which dispose 4 irensveee shaft 961 l /iounied upon. the shaft 96 is Winding drum :2? erouncl which is trained cable adopted Eor waiting blocks of ice out by the macho in order to roiete 'ihio drum the shaft a sprocket Wheel 93, and 3"!l0l! ied upon the chuil; ll" and in o iilld sprocket wheel unot' wheel 1%, the so l sprocket wheels being connected by e v n 101. our; ole clutch designated u hole by ihe ro er-once nomoral 192, associated will; x36 shaft 4-? for euggo ement vxiih iillfi sproclrel; wheel 100, and is adopted to iil'irOW lhe drum 9? into oroui; or? gear, as will be readily understood.

The invention fureher comprisee e, novel means forguicling the inuchine over the ice in a manner to cue hlcolrs of ice of uniform widths. For porpoee there is mount-ed upon the lower end sill 'Z' a pair of Werdly supporting on, s 193 103. Carried by the free ends of chose arms are ulined hearings lOilil-i, in which is jourimled short transverse urhor i055, and upon one end of the arbor mounted an auxiliary saw 106, sold sow pro ecting slightly below the base of ihe main frame, In order to drive this saw, there is mounted upon the arbor a pulley 107, which is connected. by means of u belt 108 to e pulley 109 mounted upon ihe counter-shaft 33. l iwill thus he observed lhet when the machine is moved along over the ice the sow 106 will be caused to col; ogroove in the ice. Disposed below the main frame and secured to the lower longitudinal. sills 5 and (3 thereof are longitudinal runners 110-411 respectively. The runner 1.11 which is on the right hand. side of the machine and con tiguous to the main suvv 65, is of a depth somewhat greater than -the other of said runners, and is adapted to ride in the groove formed by the saw 106. It will be seen that when the machine runs forwardly the saw 65 will out o slit in the ice and the auxiliary saw 106 will cut a groove therein. The inwmoot lll'l chine is then by the means hereinafter-dc scribed laterally shifted so that the relatively wide runner 111 seats in the groove.

The machine is then run backwardly cutting a second slit 1n the ice and the auraliary saw cutting a second groove in the ice.

The machine is then again shifted. laterally so that an runnerlll rides in and is guided by the hecond groove when the machine is to elevate the entire frame.

' Formed in the inner ends of the plates'are moved forwardly to cut the third slit in the ice. This operation is repeated as desired,

.thegrooves cut by the auxiliary saw 106 serving to guide the machine and cause it to travel in a straight lino. 4

It is often desired to shift the machine laterally, especially'vvhenblocks of greater. widths are desired to be cut. In order to accomplish such movement, it is necessary elevate the frame, there is provided at either end of the. machine, vertically movable runners which are designated as a Whole by the numeral ,112. Each of these runners is formed from a barof iron and bent into U- shaped formation to form a bight 113, which constitutes the runner, and legs 114-114:. lhe runners are disposed trans verscly of the machine and the legs are disposed'vertically, and are movably mounted between the end uprights 9-9 and 10-1O respectively. In order to guide these runners,- there is attached to each of the up rights 9 and 10 opposed plates l15115, each pair being connected to the respective Lupright by means of transverse bolts 116.

openings, which are arranged in longitudinal ahne'ment for respectively receiving longitudinal shafts 117-117. Secured upon 1 i [the shafts and between each respective pair.

of'fjolatcs 115 is a pinion 118, which meshes with a rack bar 119 that is detachably connected to the adjacent leg 114: of the runner.

' Mounted upon each of the shafts 117 is a sprocket wheels is a crossed chain 121. This sprocket Wheel 120, and trained over these chain consists of end sections 121 and 121", and the ends of these sections are respectively connected by short rods 122. These rods are adapted to meet intermediate the sprocket wheels 120, and thereby permit of said section easily passing one another. In order to actuate this chain, there is mounted upon the forward end of one of theshafts 117 a hand wheel 123. It will thus be observed that upon movement of the hand heel 123, both shafts 117 will be rotated, and through the'medium of the pinions118 the runners 112 will be elevated or lowered depending upon the direction of rotation of said hand wheel.

In order to shift the machine laterally when the runners 112 are disposed upon the ice, there is provided a longitudinal shaft 124., whichis journaled in suitable bearings In order to I manner 125-12,5 cawied by the runners 112. Mounted upoh this, shaft is a plurality of spur wheels 126, each having teeth 127 adapted for engagement with the ice. This shaft and consequently the spur wheels are manually operated by means of a. ratchet mechanism,

consisting of a ratchet wheel 128 which isv mounted upon the rear end of the shaft 124. Fulcrumed upon the shaft 124 is a hand lever 129 with which is associated a dog 130 for engagement with the teeth of the ratchet Wheel 128. It will thus be observed that upon the oscillation of the hand lever 129, the

dog 130 will engage the teeth of the ratchet;

Wheel 128 and cause the shaft 124 tc be 126 will be caused to move the machine lat f, orally.
